, current of air.

Our invention relates to water coolers and is particularly directed to that type of water cooler utilizing a heat interchange between the water'and a coolingmediumi More specifically, our invention takes the form of means permitting a heat interchange between the water to be cooled and a current of air forced into and through the water body. 7

One object of our invention is so locating the point of entrance of the water to be cooled and the coolingair, that the greatest efiiciency may be gotten. This we preferably accomplish by placing both the inlets for the air and water in the base of a water receptacle, thus allowing the air to pass upward through the body of the water to an outlet point.

Other objects are the provision of means for confining a portion of the cooled water that is free from the influence of the cooling air and also to the provision of a separate compartment in which the exhaust air may be collected and discharged after the heat interchange. I The natural tendency of heated water is to rise and in this manner leaving a cooler layer of water near the base of the receptacle. To collect and deliver the unchargedwater, we provide a supplemental receptacle in the base of the main receptacle.

Our invention is particularly eifective when replacing the ordinary radiator of an automobile and, if desired, complete circulation through the water jacket of the automobile engine may be gotten by simply utilizing the natural tendency of the heated water above mentioned. In its application to an automobile, we provide a fan element preferably driven from the crank shaft of the engine and in this manner creating a The water receptacle can be made to take the shape of the ordinary automobile front andthe current of air introduced into the bottom portion thereof. Under ordinary conditions, the tank will be filled to the desired degree and the. heated water'leaving the water jacket, would be made to also enter in the bottom of the tank. The differences in temperature between the heated and cool water, would ordinarily be sufficient to cause continuous and complete circulation of the water through the water" jackets, but the well known type of pump, when used, would, of course, supplement this action.

The preferred embodiment of our invention is shown in the accompanying drawing, in which similar characters of reference designate corresponding parts, and in which:

, Figure 1 is a perspective view of our cooler as applied to an automobile engine, and, Fig. 2 is a detached view showing the tank in section.

In the drawings, the engine is shownas comprising a cylinder 1, crank casing 2 and carrying a rigid upright standard 3. Connected to the top of the engine cylinder 1 is an outlet pipe 4 from the water jacketand extending forwardly and downwardly as at 5 and entering through the base of the water tank 6, as indicated at 7. In the adaptation of our invention to an automobile, we preferably construct the casing 6 to'conform as nearly as possible to the shape of the well known radiator since the tank is adapted to replace the same. The water entering the tank 6 is permitted to escape through aperturesq8 in the pipe 9 forming the termination of the outlet pipes from the cylinders within the receptacle. In the lower left hand corner of the receptacle 6, we provide a supplemental receptacle 10 having an open top as indicated at 11. Communicating with the base of this supplemental receptacle 10 is a water pipe 12 serving as an inlet to the water jacket of the cylinders and en'- tering the same as indicated at 13.

The standard 3 carried by the crank casing 2 serves as a bearing and support for gear mechanism, not shown, for driving a fan element 14 mounted within the casing 15 and having an open-meshwork end 16. Extending rearwardly from the casing 16 is an air pipe 17 entering the top of the receptacle 6 at 18 and continuing downwardly terminating in a T-head extension 19 apertured as at .20. The air as it is forced through the apertures 20 passes upwardly through the body of the water and collects in the upper portion of the tank 6. To prevent excessive splashing and to permit the ready escape of this air, we provide a partition 21 apertured as at 22 and forming pure airmay the air exhaust chamber 28. Entering the exhaust chamber 23 at 24: and 25 are relief pipes 26 uniting as at 27 into a common pipe 28 extending'downwardly any desired distance to a point remote from the working mechanism of the automobile. In order to secure a maximum cooling effect, we provide supplemental air conduits 29 extending" transversely of the tank and permitting the passage'of a current of air through the same and into the compartment formed by the hood of" the automobile. In this manner be supplied to the fan structure.-

The operation of our device is as followsi The casing 6 beingnormally filled as indicated in the drawing, the heated water leaves the engine. cylinder and enters the base of the tank through the apertures 8 in the pipes 9 and passes upwardly to the water level. During this operation, however, the

a fan 14 directly drivenfrom the crank shaft, 1 causes a current of air to also be introduced point.

intothe bottomof the receptacle .6.thr0ugh the apertures 20in the pipes 19. The air being considerably lighter than the water, will naturally pass upward to an outlet The, close mingling of the water and air causes a heat interchange by cooling the water and heating the air and the cooled water will naturallyv collect in the bottom of the tank. The water after it has been a cooled and that which enters the supplemental receptacle 10 is free from the action of'the cooling air and consequently cannot carry any of the cooling air into the engine cylinder. The air as it escapes after the cooling action, enters the compartment 23 through the apertures 22 in the wall 21 and passes out to the open air. It will be under- Gopies of this patent may be obtained for stood, that complete circulation of the water through the engine Water jackets may be had by taking advantage of-the difierence in temperature of the water before and after it is cooled, but this circulating action may be supplemented by using the well known perforated airinletpipe in the base of said receptacle, a cool water compartment haw ing'an open top and closed sides and bottom in the base of said receptacle, the top of said compartment being above the level of'said air inlet pipe, said air inlet pipe being confined to the space in the base of said receptacle not covered by said compartment,

means for forcing a stream'of airthrough said air inlet pipe, means for-supplying water to said receptacle, and a water outlet pipe leading from the base of said receptacle.

In testimony whereof we afliX our signatures in presence of two witnesses.
